To Whom It May Concern:
Although he arrived recently in the company, I would like to recommend Mr John Doe as a candidate for a position with your organisation.
John knew how to easily and quickly find his place in instructors' team already in position. He showed a big adaptability, in particular in the apprenticeship of the procedures implementation for the management of the simulators and the accompaniment of the customers. John handles delicate customer relationships with utmost care and empathy and always ensures that clients are satisfied.
If John's performance in our firm is a good indication of his future performance, he would be an extremely valuable asset to your company. If I can provide you with any further information, please do not hesitate to contact me.
Sincerely,
